Hi Niels,
Thank you so much for copying the message!
I am still personally very worried about even the modified version. Based on the (possibly) new #18b, it seems that any fMRi experiment with between-subjects design would be clinical trials. Even if it did not state clearly whether within-subjects design make participants "prospectively assigned to an intervention" (it sounds likely so), it would still mean many of the experiments we see in the literature would fall in the basket of clinical trials.
